This is Dr. David
some impetigo infections can cause facial swelling.
some people can also be allergic to mupirocin or bactroban antibiotics which can cause facial swelling.
you should bring her back to the ER or urgent care center
and see if she may be allergic to something.
she may need steroids or stronger anti-histamine treatment
I would go to an ER to get assessment for her facial swelling now
let me know if you have other questions.
